Ju Yong Cheong, Christopher J Young
PURPOSE: Hand-assisted laparoscopic surgery (HALS) is a minimally invasive surgical technique with the combined benefits of laparoscopic surgery while allowing the use of the surgeon's hand for better tactile control. Obesity has been associated with higher conversion rates with multiport laparoscopic surgery, but not with HALS. This study aimed to examine the versatility of HALS in various clinical contexts. METHODS: All HALSs performed at 2 major tertiary centers in Sydney were prospectively collected for retrospective analysis...

Rectal neuroendocrine tumor (NET) is a relatively rare lesion of the gastrointestinal tract, but the prospective examination with colonofiberoscopy or endoscopic ultrasound has increased the frequency of its detection. It is often difficult to determine the optimal treatment for NETs sized <20 mm in the clinical setting. Other clinicopathological variables are not considered in the current guidelines and staging systems. Although the effects of lymphovascular invasion are not covered by the World Health Organization (WHO) 2010 guidelines or tumor-node-metastasis (TNM) staging system, this may be promising for the establishment of improved guidelines and staging systems, particularly for early-stage colorectal carcinoids...

The newly characterized modified frailty index (mFI) is a robust predictor of postoperative outcomes for surgical patients. The present study investigates the optimal cutoff for mFI specifically in older gastrointestinal (GI) cancer patients undergoing surgery. All patients more than 60 years old who underwent surgery for a GI malignancy (esophagus, stomach, colon, rectum, pancreas, liver, and bile duct) were identified in the 2005 to 2012 National Surgical Quality Improvement Program, Participant Use Data File (NSQIP PUF)...

Laparoscopic restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) constitutes a curative treatment option for therapy-refractory ulcerative colitis. A two-stage procedure with loop ileostomy at the time of IPAA is the most frequent variant of surgery. The aim of the procedure is the complete removal of the colon and rectum with simultaneous restoration of gastrointestinal continuity and preservation of continence functions. Long-term quality of life following laparoscopic proctocolectomy with IPAA is good and comparable with a healthy reference population...

A 27-year-old female heroin addict presented with a peritonitic and distended abdomen. Her medical history included depression and a 3-year history of heroin abuse with attendant constipation. CT scan showed free intraperitoneal gas, massive faecal distension of the rectum and sigmoid colon and likely bowel necrosis. She underwent an emergency Hartmann's procedure for perforation of the sigmoid colon. Pathology identified two areas of stercoral ulceration, one of them being the area of perforation. Postoperatively, the patient developed a deep vein thrombosis and is now on anticoagulant therapy...

BACKGROUND: Increased defecation frequency and soiling are common complications of surgery for right-sided Hirschsprung's disease (HD). Though the laparoscopic Duhamel procedure is a favorable option in right-sided HD, the conventional laparoscopic technique is time consuming and has complications that are associated with the reservoir. In this study, we described a modified laparoscopic Duhamel technique with ex-anal rectal transection combined with the Deloyer's procedure for right-sided HD...

Surgery is the mainstay curative treatment in most cancer. We aimed to test the new hypothesis that cancer surgery performed during holiday periods is associated with worse long-term prognosis than for non-holiday periods. This nationwide Swedish population-based cohort study included 228,927 patients during 1997-2014 who underwent elective resectional surgery for a cancer where the annual number of resections was over 100. The 16 eligible cancer sites were grouped into 10 cancer groups. The exposure, holiday periods, was classified as wide (14-weeks) or narrow (7-weeks)...

BACKGROUND: Multiple lymphomatous polyposis is a rare type of gastrointestinal lymphoma that extensively infiltrates the intestine. Multiple lymphomatous polyposis originates from the mantle zone of the lymphoma follicle and is considered to be a mantle cell lymphoma, which is a relatively aggressive type of B-cell non-Hodgkin's lymphoma. We report an unusual case of a patient with multiple lymphomatous polyposis with extensive colorectal involvement and acute intestinal obstruction, an atypical complication of this rare disease...

BACKGROUND AND STUDY AIMS:  Recent studies suggest that differences in biological characteristics and risk factors across cancer site within the colon and rectum may translate to differences in survival. It can be challenging at times to determine the precise anatomical location of a lesion with a luminal view during colonoscopy. The aim of this study is to determine if there is a significant difference between the location of colorectal cancers described by gastroenterologists in colonoscopies and the actual anatomical location noted on operative and pathology reports after colon surgery...

Stephen Alexander Boyce, Craig Harris, Andrew Stevenson, John Lumley, David Clark
BACKGROUND: Anastomotic leak after colorectal surgery increases postoperative mortality, cancer recurrence, permanent stoma formation, and poor bowel function. Anastomosis between the colon and rectum is a particularly high risk. Traditional management mandates laparotomy, disassembly of the anastomosis, and formation of an often-permanent stoma. After laparoscopic colorectal surgery it may be possible to manage anastomotic failure with laparoscopy, thus avoiding laparotomy. OBJECTIVE: The purpose of this study was to determine the feasibility of the laparoscopic management of failed low colorectal anastomoses...

BACKGROUND: Despite the proven benefits, laparoscopic colorectal surgery is still underutilized among surgeons especially in developing countries. Also a steep learning is one of the causes of its limited adoption. OBJECTIVE: To explore the learning curve of single surgeon experience in laparoscopic colectomy and feasibility of implementing a well standardized step by step operative technique to overcome the beginning technical obstacles. PATIENTS AND METHODS: This prospective study included 50 patients with carcinoma of the left colon and rectum recruited from the department of surgical oncology at National Cancer Institute, Cairo University in the period 2012-2016...

Osseous metaplasia (OM) is rarely observed in colorectal cancer (incidence < 0.4% in rectal cancer), where it has a non-specific clinical presentation and unknown pathogenesis. Here, we report three cases of colorectal carcinoma with OM and propose a new hypothesis. All three patients (two males and one female) were Chinese and had different sites of colorectal carcinoma with OM: rectum, sigmoid colon, and appendix. The pathologic diagnoses were serrated adenocarcinoma; moderately to poorly differentiated adenocarcinoma with micropapillary carcinoma and cribriform comedo-type adenocarcinoma; and mucinous adenocarcinoma, respectively...
